The Effects of Dynamic Network Loading Models on DTA-based OD Estimation

Abstract

Congestion causes substantial economic losses, both for individual and commercial transport. This chapter will examine the effect of using different queue mechanisms in the dynamic network loading (DNL) models on the dynamic origin destination (OD) estimation problem on different test networks. The chapter begins with a short review of OD estimation methods based on traffic counts, followed by a discussion of the different dynamic network loading models and the solution algorithm used in this chapter. Next, the effect of choosing one of the above mentioned queuing approaches is examined by solving the OD estimation problem on different test networks. In the last section of the chapter the authors formulate conclusions along with possible future research.
